Toalwhamania Be it known that I, v Rica-uu) G.. Caron,

.citizen of the United States, residing at Palmyraggin the county of=Wayne and ,State 'of New `-York, have invented certain new and useful'Improvements in Faucets, of which theA following isaspecification.`4

My inventldnrelat to-improvements in elfected automatically through thecombined action` of waterepressure'I and a coiled 'cx- The object of theVimprovements, which form'the'subject matter ofthis application to`rodueeravs'elf-closin lfaucet having the fo lewin principal avantages1The 'which' projects a lug 9 on which is enforced apualmovement of the faucet lever-whic operates the piston. whereby the.

operator may draw any size'stream' and stop at any desired pointwithequal facility irrespective of the liquid pressures. A faucet soconstructed as to insure a long life and prevent leakage around thevalve and its seat. A' faucet in which the operator does not havetocontend with the pressure of the flowing liquids# A faucet theessential parts of which ma .eine so adjusted as to decrease the flow ofiquid due to a high pressure. A.. construction in which water hammer infaucet or pipes i's prevented and one in which the parts are readilyaccessible and easily repaired.

In the accompanying drawing,-I have illustrated my inventionein apreferred form in the followingviews:`

Figure 1 is ajside elevation of my 'imroved faucet in its closedposition; `i'g. 2 1s a longitudinal section through said faucetin'closed position; Fig. 3 is a detail of an innercy'linder which formsan important feature of my invention.

Referring to the details of the; drawing 4 represents a nipple which isformed with aiexternally threaded extension 5. a squared portionvG-,andis adapted to be screwed Vuponrthe. faucet body-7. This body is formedvwith a discharge nozzle v8 -from lvoted alever 10, the pivot.pin 11passing t rough a slot 10 in the lever. Pivotally connected with thislever is a valve-rod 12 `.'vhich passes through asuitable bearing in agland 13 which is screwed into the outer 'end of the body 7, and alsothrough a loose washer 14' which is seated in the said body. O

15 represents a piston which is' screwed .upon -the -and has extendinreduced inner' end of -tlie 'rodifl 'axially therethrough' small port16. ounted-onthe 'rodf12b'evtween the piston Iii-*and a' washer .18-is arubber valve 17 which seats upon the valve-: seat 17a formed ontlieinner. walls/oi the faucet to cover and uncover the passageway throughthe latter. Surroundingthe rod.12.

is an expansion coil-springr 19 one Aendofwhich bears against an annularshoulder-7*. y

formed o'n the. inner walls of theifaucetbody, and the'other endagainst'apin 25 which passes through the rod 12. ,The

vgland 13 is chambered on its under .side to;

provide for the insertion .of aching` 20- which is expanded and held uner pressure against the washer' 14'byf screwingfup their and.v

21' represents a cup-shapedcylinder which forms an important feature ofmy invention; This member is of less cross diameter than thecorresponding diameterof the nipple 4 thus leaving an annular passa ewaybe-` tween the inner walls of the nipp e and the outer walls of thecylinder. The inner walls of the cylinder are ground to make a sliding.lit for t l in. Through the walls of this cy one or more triangular-shaed s bases of which are toward t e closed end or bottom of the c linderon which a slotted boss 23 is provi ed to facilitate the adjust` ment'of said cylinder in the nipple. The' cylinder is externally threadedaround itsA open end vas at 24 to en a e the female threads onthe innerend o t e nipple.

From the construction shown and described, it will be apparent that thepiston 15 may be adjusted relative to the ports 22 inder are ots 22 thee piston 15 which is arran ed therein the cylinder, so as to entirely oronly I partiall uncover same as may be desire The adjustment of thepiston on the stem 12 also controls the position of the valve 17 so thatthe latter-,may be caused to travel' a greater or less distance relativeto its sextV piston from be- 'rios ports 22 remaining covered untilVafter the E valve 17 leaves its seat, makes it easy to control the valvelever. The valve when open, l ifV held in a central position vwithliquid; `flowing in front of same past its conicall face, assists thelever against the reaction 2 of the spring, which is at itsgreatesttension at this time. The valve is far enough removed from thescat, before the flow of VWater through the ports, equals the ksize ofthe passage,f to prevent its being forced violently upon its back seat.The hydraulic relief through the hole in the piston prevents too rapidclosing of the valve, and

avoids Water hammer. In closing the faucet the momentum of the Waterthrough the pipe is checked gradually, because the piston closes. thetriangular ports .from base to apex. The Water pressure coming ont-hesides of the piston,'avoids pressure from the rear. The piston rod,being'guided at both ends, causes the valveto always seat in the sameposition, insuring a longer life, and' more perfect it. As the pistondoes not it tightly in the c linder, the slight leakage finally assistst e spring in seating the valve.

The action of the various parts of my improved faucet is'so apparentfrom the construction that further description would seem superliuous.

Having thus described my invention what I claim as new, is y 1. In afaucet having a body and a disranged in said body and having lateralports therein, an adjustable piston slidably mount- -.ed in saidcylinder and adapted to control said ports, a. valve in'said cylinder,and a lever. for operating said piston and valve.

2. In a faucet having a body anda discharge nozzle, au. adjustablecup-shaped cylinder arranged in said body and having therein lateralports .of varying area, an adjustable piston slidably mounted in saidcylinder and adapted to control said' ports, a Avalve in said cylinder,and common means for operating said pistou and valve.

3. In a faucet having a body'and a discharge opening and nozzle, acylinder adjustably arranged in said body and ,having therein trianvularports, a piston mounted in said cylinder and adapted to control saidports, a Y. lve arranged to control said discharge opening, and a leverfor operating said piston and valve.

4. In afaucet havin a body and a disehar e nozzle, a 'cupaped. cylinderadi just ly arranged jin said bodyand havin lateral ports therein, a rodmountedin said body, a piston ou said rod adapted to con'- trol saidorts, a valve on said rod adapted to contro the passaoe ofliuid throughsaid faucet, and meansor operating said rod.

In testimony whereof I aix my signature in the presence of twofwitnesses.
